Concatenation and repetition of animations is not applied

My attempts in creating an animation with multiple stages or with repetition have failed. The following is an example of both concatenation and repetition:

Animate.Property(tb2, Canvas.LeftProperty, g, 0, new LinearDoubleEasing(), TimeSpan.FromSeconds(3))
       .Merge(Animate.Property(tb, Canvas.LeftProperty, 0, -g, new LinearDoubleEasing(),
                               TimeSpan.FromSeconds(3)))
       .Concat(Animate.Property(tb2, Canvas.LeftProperty, 0, -g, new LinearDoubleEasing(),
                                TimeSpan.FromSeconds(3))
                      .Merge(Animate.Property(tb, Canvas.LeftProperty, g, 0,
                                              new LinearDoubleEasing(),
                                              TimeSpan.FromSeconds(3))))
       .Repeat()
       .Subscribe();

In this example, the Merge is working correctly and both controls move to the left as specified in the first two lines, but once that part is done executing, the animation stops. Even removing the Concat and using Repeat alone (with or without a parameter) does not help.

Am I doing something wrong here?

Sure, we can close this. Thanks!
